Hot-knife techniques can also be used with Vectran in rigid composite laminates. Organic fibers such as aramid or LCP often leave a rough or ragged edge after net-shape cutting with a high-speed saw because the fibers are difficult to cut. The edges of composites containing Vectran can be melted using a hot knife to remove the excess fiber, resulting in a cleaner edge and more acceptable finished part.
Through its new materials testing program, HSGM helps companies select the right cutting machine and blade for their specific applications. The company recommends two of its units for cutting Vectran, the HSG-1-VW or HSG-03-VW, with blade type HSS15°-7mm.
HSGM's cutting system works by heating a blade with a transformer for up to eight seconds at about 600 degrees Celsius, melting all thermoplastic fabric that comes into contact with the tip. A consistent sealed edge is formed in a webbing when the individual weft and warp threads naturally flow into each other.
Heissschneide- Geräte und -Maschinen, an independent organization within the ENGEL Group, has been in operation since 1977. The company develops, produces and sells heat cutting machines and equipment, fixtures and machines for cross-directional and straight-line cutting, automatic length cutting machines for ropes and belts, form cutters and form cutting machines, soldering and Styrofoam cutting equipment as well as single-phase and three-phase transformers.
